Austin's Algae: Is Tap Copper Fueling Summer Eyes?
By Franklin Everett ShawThe summer heat in Austin isn’t just about the temperature; it’s about the water. Specifically, what’s in the water. We’ve all heard whispers about the tap water, but lately, the murmurs have turned into a chorus of complaints: itchy eyes, red eyes, even infections. Could the water be to blame? And if so, what’s the culprit?
The finger is pointing at copper.
Austin’s aging infrastructure, particularly in older neighborhoods like Hyde Park and Travis Heights, means copper pipes are still common. These pipes, over time, can leach copper into the water supply. While copper is an essential nutrient in small amounts, elevated levels can wreak havoc, especially when combined with the algae that thrive in Texas summers. This article will dive deep into the potential link between Austin’s tap water, copper levels, and the recent surge in algae-related eye issues. We’ll provide actionable steps you can take to protect yourself and your family.
First, let’s talk testing. You can’t fight an invisible enemy without knowing it’s there. The City of Austin provides water quality reports, but these are averages across the entire system. Your home’s water could be significantly different. The most reliable way to know your copper levels is to test your own tap water.
You have two main options: a DIY test kit or a professional lab test. DIY kits, available at most hardware stores like Home Depot or Lowe’s in Austin, are relatively inexpensive (around $20-$50) and easy to use. However, their accuracy can be limited. They often provide a simple “pass/fail” result or a broad range, which isn’t ideal for precise monitoring.
A professional lab test, while more expensive (typically $50-$100), offers a much more accurate and detailed analysis. Look for labs certified by the EPA, such as those listed on the Texas Commission on Environmental Quality (TCEQ) website. These labs will provide a report with specific copper levels in parts per million (ppm).
To collect a sample for either type of test, follow these steps carefully:
- Use a clean, unused container provided by the test kit or lab.
- Let the water run for 3-5 minutes to flush out any stagnant water in your pipes. This is crucial for getting a representative sample of your water supply.
- Collect the sample from a frequently used tap, such as your kitchen sink.
- Follow the specific instructions provided with your test kit or lab for filling the container and submitting the sample.
A common mistake is not flushing the pipes adequately before collecting the sample. This can lead to artificially low copper readings. Another pitfall is using a contaminated container. Always use the container provided by the test kit or lab, or a thoroughly cleaned container that has not been used for anything else.
Now, let’s understand why copper might be contributing to these eye problems. Copper, even at slightly elevated levels, can act as a catalyst for algae growth. Algae, particularly blue-green algae (cyanobacteria), are common in Austin’s lakes and rivers, and can sometimes find their way into the water supply, especially during the hot summer months.
Copper can disrupt the cell membranes of algae, releasing toxins into the water. These toxins, along with the algae itself, can cause eye irritation, redness, and even infections, especially for contact lens wearers. Contact lenses can trap algae and toxins against the eye, exacerbating the problem.
Furthermore, copper itself can be an irritant. While the EPA’s maximum contaminant level for copper in drinking water is 1.3 ppm, some individuals are more sensitive to copper than others. Even levels below the EPA limit can cause irritation in sensitive individuals.
So, what can you do if you suspect your tap water is contributing to your eye problems?
First, consider your contact lens hygiene. This is paramount. Always wash your hands thoroughly before handling your lenses. Use only sterile contact lens solution to clean and store your lenses. Never use tap water to rinse your lenses or lens case. Tap water can contain microorganisms, including algae, that can contaminate your lenses and cause infections.
Consider switching to daily disposable lenses. This eliminates the need for cleaning and storage, reducing the risk of contamination. If you experience any eye irritation, remove your lenses immediately and consult an eye doctor.
Next, explore water filtration options. Not all filters are created equal when it comes to removing copper. A basic pitcher filter, like a Brita, may not be sufficient. Look for filters certified to NSF/ANSI Standard 53 for copper reduction. These filters use activated carbon or other filtration media to effectively remove copper from your water.
Whole-house filters are another option, but they are more expensive and require professional installation. However, they filter all the water entering your home, providing protection from copper and other contaminants throughout your entire plumbing system.
Reverse osmosis (RO) systems are highly effective at removing copper and other contaminants, but they can be expensive and require significant plumbing modifications. They also remove beneficial minerals from the water, so you may need to supplement your diet.
A common mistake is assuming that any water filter will remove copper. Always check the filter’s certification and specifications to ensure it is designed to remove copper. Another pitfall is neglecting to replace your filter cartridges regularly. Over time, filter cartridges become saturated and lose their effectiveness.
Finally, consider reporting your concerns to the City of Austin. If you suspect that your tap water is contaminated with copper or algae, contact Austin Water. They can investigate the issue and take corrective action if necessary. Collective reporting can help identify problem areas and prompt the city to address infrastructure issues.
Don’t underestimate the power of community awareness. Talk to your neighbors. See if they are experiencing similar issues. Sharing information and experiences can help identify patterns and potential sources of contamination.
The link between copper, algae, and eye irritation in Austin’s tap water is a complex issue. While more research is needed to fully understand the extent of the problem, taking proactive steps to test your water, improve your contact lens hygiene, and filter your water can help protect your eyes and your health. Don’t wait for the problem to get worse. Take action today.
